Repetition blindness for emotion words: Exploring interactions between valence and arousal

Emotional information is treated differently than any other type of information and has a powerful impact on many cognitive processes, including attention. The aim of this study was to investigate how valence and arousal impact how we process words in sentences, as well as examine two theories of emotion, categorical negativity theory and the arousal hypothesis. Categorical negativity theory suggests that the valence of a word is what truly influences how emotional information receives attention, while the arousal hypothesis posits that the arousal level of a word determines the amount of attention it receives. In the current work, we used the rapid serial visual presentation (RSVP) task to investigate interactions between valence and arousal. The valence and arousal levels of positive and negative emotion words were manipulated within the context of full-sentence reading. Analyses revealed that all negative words, regardless of arousal level, produced the standard repetition blindness effect; however, positive words appeared to benefit from repetition. This interaction of valence and arousal suggests that a new theory is needed to accommodate evidence that both valence and arousal play a role in the attentional capture of emotion words.
